effects of grinding media shapes on ball mill performance Know More milling, its contribution and effect on milling kinetics, load behaviour and mill power is not fully grinding. Ball size distribution inside an industrial mill was analysed in terms of shapes and sizes.
Get MoreModelling of the Performance of AG/SAG Mills
A new ag/sag mill model has been developed which is based on the dynamics of the grinding charge as well as its size distribution and composition. The effects of changes in such operating conditions as feedsize distribution and ball charge level are inherently described within the model as is the effect of changes to the height and shape of the lifters.
